Filed July 7, 1967, Ser. No. 651,860 1 Claim. (CI. 33-23) ABSTRACT OFTHE DISCLOSURE An adapter for a conventional scriber including a portionadapted Ito be removably supported from a scriber in lieu of a pencil orpen element of the scriber and to support a felt tip marker therefromwhereby the scriber may be utilized to guide the movement of the felttip marker- The instant invention includes the provision of an adapterfor a conventional scriber in the form of an assemblage adapted toremovably support a felt tip marker therefrom and which includes meanswhereby the assemblage may be supported from a conventional scriber inlieu of the pen or pencil element normally supported by the scriber. Bysuch an assemblage a felt tip marker may be utilized in conjunction witha scriber to form the letters of signs and other printed material in aprofessional-like manner.

The main object of this invention is to provide a means by which aconventional felt tip marker may be supported from a conventionalscriber in lieu of the pen or pencil unit normally supported from thescriber.

Another object of this invention is to provide an assemblage inaccordance with the preceding object which may be constructed in amanner so as to support various felt tip markers therefrom.

Still another object of this invention is to provide an assemblageconstructed in a manner such that a conventional scriber may be readilyadapted to support a felt tip marker therefrom.

A final object of this invention to be specifically enumerated herein isto provide an assemblage in accordance with the immediately precedingobjects which will conform to conventional forms of manufacture, be ofsimple construction and easy to use so as to provide a device that willbe economically feasible, long lasting and relatively trouble-free inoperation.

These together with other objects and advantages which will becomesubsequently apparent reside in the details of construction andoperation as more fully hereinafter described and claimed, referencebeing had to the accompanying drawings forming a part hereof, whereinlike numerals refer to like parts throughout, and in which:

FIGURE 6 is a perspective view of the assemblage illustrated in FIGURE 5by which the felt tip is supported from the modified form of scriber;

FIGURE 7 is a perspective view of still another modified form ofassemblage by which a felt tip marker may be supported from the scriberillustrated in FIGURES 1 and 2; and

FIGURE 8 is a perspective view of a fourth modified form of assemblagefor supporting a felt tip marker from a conventional form of scriber.

Referring now more specifically to the drawings the numeral 10 generallydesignates a conventional form of scriber including a main body portion12 from which a guide pin assembly 14 is supported. The main bodyportion 12 also supports a tracing pen 16 and a pivoted support armstructure 18 which may be secured in adjusted rotated positions relativeto the body portion 12. The support arm structure 18 includes abifurcated free end portion including a pair of furcations 20 and 22interconnected by means of a clamping screw 24. The free ends of thefurcations 20 and 22 include opposing semi-cylindrical recesses (notshown) in which a cylindrical member may be secured in adjusted rotatedposition relative to the support arm structure 18.

A generally cylindrical pencil or pen assembly is conventionally clampedbetween the free ends of the furcations 20 and 22. However, in order toadapt the scriber 10 to support a felt tip marker such as that generallydesignated by the reference numeral 26 illustrated in FIGURES 1-3, anassemblage generally referred to by the reference numeral 28 isprovided. The assemblage 28 comprises a split clamp assembly including apair of generally semi-cylindrical resilient arm portions interconnectedat one pair of adjacent ends. The free end of one of thesemi-cylindrical arms or arm assemblies is notched and rolled outwardlyand back upon itself tightly about a pivot pin 30 to which one endportion of an elongated spring latching member 32 is pivotally securedin the notched area of the rolled portion of the one arm assembly andthe free end of the other arm or arm assembly is also notched and rolledoutwardly and back upon itself to tightly clamp a latch pin 34 whichgenerally parallels the axis of rotation of the latching member 32 andwith which the hook end portion 36 of the latching member 32 may bereleasably engaged to circumferentially contract the assembly 28 aboutthe felt tip marker 26. The assemblage 28 includes an integral sleeveportion 38 remote from the free ends of the arms or arm assemblies whichsupport the pins 30 and 34 and one end of a generally cylindricalsupport rod 40 is stationarily secured in the sleeve portion 38.

The extended end of the support rod 40 is of a diameter adapted to beclamped between the aforementioned semi cylindrical recesses formed inthe free ends of the furcations 20 and 22 and therefore the screw 24 maybe utilized to cause the support rod 40 to be clamped between thefurcations 20 and 22 and to thus support the felt tip marker 26 from thescriber 10 by means of the assemblage 28.

With attention now invited more specifically to FIG- URES 5 and 6 of thedrawings there may be seen a modified form of scriber generally referredto by reference numeral 10' and which includes furcations 20' and 22similar to the furcations 20 and 22. The furcations 20' and 22 alsoinclude recesses (not shown) similar to the aforementioned recessesformed in the free ends of the furcations 20 and 22 and a split sleevetype assemblage generally referred to by the reference numeral isremovably clamped between the furcations 20' and 22'.

The split-sleeve type assemblage 50 includes a generally cylindricalbody portion 52 including a diametrically en- 3 larged shoulder 54 onone end. The body portion 52 and the shoulder 54 are longitudinallysplit as at 56 and therefore the body portion 52 may becircumferentially contracted when clamped between the furcations 20' and22'. A felt tip marker generally referred to by the reference numeral 58and which is somewhat smaller in diameter than the felt tip marker 26 isdisposed within the body portion 52 whereupon the clamping action of thefurcations 20' and 22' will cause the felt tip marker 58 to be clampedin the body portion 52. Of course, the shoulder 54 carried by the upperend of the body portion 52 is adapted to abut and rest against theadjacent upper surface portions of the furcations 20' and 22'.

With attention now invited to FIGURE 7 of the drawings there may be seenan assemblage referred to in general by the reference numeral 60 andwhich is similar to the assemblage 28 except that in lieu of a pair ofspring arms the assemblage 60 includes a continuous sleeve member 62from which a support rod 64 similar to the support rod 40 is supported.The sleeve member 62, instead of defining a clamp assembly includesinwardly projecting circumferential ribs 66 spaced longitudinallytherealong which are adapted to frictionally engage and thus removablyretain the felt marker 26 within the sleeve member 62.

With attention now invited more specifically to FIG- URE 8 of thedrawings there may be seen an assemblage generally referred to by thereference numeral 68 and which is quite similar to the assemblage 60except that in .lieu of the axially spaced and circumferentiallyextending ribs 66 for frictionally retaining the felt tip marker 26therein, the sleeve member portion 70 of the assemblage 68 includesthread means 72 defining threads of relatively great pitch which may beutilized to removably threadedly secure a modified form of felt tipmarker provided with similar external threads. Of course, the relativelygreat pitch of the thread means 72 enables a corresponding felt tipmarker such as the marker 26 but provided with similar external threadsto be quickly removably secured in the sleeve member 70 of theassemblage 68.

The foregoing is considered as illustrative only of the principles ofthe invention. Further, since numerous modifications and changes willreadily occur to those skilled in the art, it is not desired to limitthe invention to the exact construction and operation shown anddescribed, and accordingly all suitable modifications and equivalentsmay be resorted to, falling within the scope of the invention asclaimed.

What is claimed as new is as follows:

1. In combination with a scriber 0f-the type including a clamp assemblyadapted to removably clampingly engage a pencil or pen element of arelatively small diameter, an adapter holder comprising a sleeve memberadapted to encircle a second relatively large diameter size felt tipmarker, said sleeve member being split, resilient and including spacedapart free ends, said sleeve member including a shank portion carried bya portion thereof generally diametrically opposite said free ends, saidshank portion generally paralleling the longitudinal center line of saidsleeve member and including one end portion projecting endwise outwardlyof the corresponding end of said sleeve member, said one end portion ofsaid shank portion being of a diameter generally equal to said smalldiameter, said oneend portion being removably clamped in said clampassembly, a hooked latching member including a shank end and a hookedend, the shank end of said latching member being articulatively anchoredto one of the free ends of said sleeve member centrally intermediate theaxial ends of said sleeve member, the other of said free ends of saidsleeve member being notched centrally intermediate the axial ends ofsaid sleeve member and rolled outwardly and back upon itself, a latchpin secured in and at least substantially encircled by the rolledportion of said other free end of said sleeve member, the free hookedend of said latching member being removably engaged with the portion ofsaid latch pin extending through the notched area of said rolled portionof said other free end with said sleeve member circumferentiallycontracted so as to be adapted to tightly clamping engage said marker.
